At a glance
| Generic name | Onabotulinum Toxin A |
|---|---|
| Also known as | BTX-A, Botox, BOTOX |
| Sponsor | Walter Reed National Military Medical Center |
| Drug class | Botulinum toxin |
| Target | SNAP-25 (synaptosome-associated protein of 25 kDa) |
| Modality | Small molecule |
| Therapeutic area | Neurology, Dermatology, Ophthalmology |
| Phase | FDA-approved |
Mechanism of action
The toxin is a zinc-dependent endopeptidase that cleaves SNAP-25, a protein essential for acetylcholine vesicle fusion and release. This prevents neuromuscular transmission, resulting in flaccid paralysis of injected muscles. The effect is temporary, lasting 3-4 months, after which nerve terminals regenerate and muscle function returns.
